Tube and Pipe Fabrication

The tube and pipe fabrication technology area covers sawing (band, circular, and friction) and other cutting processes, such as abrasive, flame, laser, oxyfuel, plasma, and waterjet. It also discusses forming processes, including bending and end forming. Finally, it includes a handful of miscellaneous processes, such as trimming, beveling, finning, grooving, threading, and spinning.

Feeding the process

July 9, 2010 | By George Winton

Whether a bending process starts with a cut length of tubular product or a coil, gravitational or torsional forces can lead to unwanted variations in the finished product. In the case of gravity, tube supports can counteract it; for torsion, it’s a matter of matching the coil’s output to the bender’s input.

Doing more with less

April 29, 2010 | By George Winton

Loading and unloading tube for fabricating often is a manual process. Because labor rates in the U.S. are higher than those in many other countries, manual loading and unloading isn’t competitive. Using an automatic loader/unloader can change that, moving an operation from red to black.

Selecting the right mandrel and wiper

April 1, 2010 | By William Q. Tingley III

Tube bender operators could rely on complex mathematical formulas and rules of thumb, but it’s much quicker to use a tooling chart. This sort of chart lists the two main bending criteria, D of bend and wall factor, on the X and Y axis, respectively. However, these charts have just two axes, and usually are based on bending mild steel to 180 degrees. Tube bending comprises many more variables, materials, and bend angles. Knowing how to make adjustments to compensate for additional factors is critical for successful bending.
